🕜 Hi, the current time is about a half past seven in the evening 🌇.

o álbum do vídeo é este: https://mads-kjeldgaard.bandcamp.com/album/space-in-between

Ok mais logo faço aqui um fio com os pormenores, mas pra já deixem-me mostrar-vos o setup que desde há muito quis ter para escrever no computador, inspiradíssimo no OmmWriter, usando só ferramentas livres.

O editor é o FocusWriter, a banda sonora é do @mads100tist@mads100tist e os sons do teclado vêm de uma biblioteca caseira que alinhei, usando samples do snd.dev

@zotero@zotero I noticed that some combinations of XFCE appearance (light) themes and Zotero made the menu “disappear” (black on black) as the window title was dark. Changing the Zotero to a dark theme or changing the XFCE theme worked (but then, I liked the dark window title on a light theme best…). Should I try to open an issue about this, or is it a XFCE issue? I don’t want to burden the maintainers but it was a bit disturbing not to find the menus…

@movq@www.uninformativ.de Pretty sure all my mu solutions are very slow, but not so slow as I optimized most of the implementations to avoid as much brute forcing as I could.

“Audaz”, Público, a palavra que procuram é “audaz”. Não vale de muito as regulares colunas de defesa da língua portuguesa quando depois é pontapés destes

Anteontem concretizei finalmente uma ideia de há anos – uma pequena biblioteca #python para emitir sons com cada tecla que pressionamos. Espero logo ter energia pra gravar um pequeno vídeo de demo e publicar o repositório

@prologic@twtxt.net It is, yes.

@movq@www.uninformativ.de This is the total amount of cpu time consumed right?

I rewrote all my solutions in Rust (except for day 10 part 2) and these are the runtimes on my i7-3770 from 2013 (this measures CLOCK_PROCESS_CPUTIME_ID, not wallclock):

I like this. You get performance that’s more or less in the ballpark of C, but without the footguns.

@movq@www.uninformativ.de Hmmm 🧐

If your very popular project with lots of stars on GitHub is over 10 years old, and you’re still at a pre-1.0 version because you’re using SemVer and a 1.0 would mean making some kind of commitment and that’s somehow not desirable for you, then I think you’re doing something wrong. 🤔

Got a nice conspiracy theory for you:

Actually wait I just thought about this and realized that the precise timing of the ACTUAL GitHub seed bank, by which I mean the Arctic Code Vault, on 2020-02-02, makes it more or less a perfect snapshot of pre-Copilot GitHub. Also precisely timed before we all got brain damage from COVID. This is the only remaining archive of source code by people with a fully working sense of smell

(Bonus points because the Arctic World Archive is located in Svaldbard and that’s the name of the AI in Stacey Kade’s “Cold Eternity”.)

#Processing & #py5 tip:
Remember the shapes you put on draw() will be redrawn over and over, and if they don’t move (leaving a trail) you might want to either clean each frame with background(...), or stop the draw loop (noLoop() in Processing or no_loop() in py5), otherwise you kill the anti-aliasing of the lines/strokes/edges!

I’m posting this tip because even using these tools for years and knowing this, today I briefly thought something was odd/broken because my lines were ugly with no “smoothing” :D

”`python
import py5

def setup():

py5.size(200, 200)
py5.stroke_weight(2)
# a line that will drawn once only
py5.line(10, 10, 190, 90)  

def draw():

# you could clean the frame here with background(200)
# this other line will be redrawn many times
py5.line(10, 110, 190, 190) 

def key_pressed():

py5.save('out.png')

@kiwu@twtxt.net evening!!!

@prologic@twtxt.net How on earth did you do that so quickly, especially day 10? People were struggling with this a lot. 🤯

@movq@www.uninformativ.de Haha 😆

@prologic@twtxt.net Jesus, that was quick. 😅

I cleaned up all my of AoC (Advent of Code) 2025 solutions, refactored many of the utilities I had to write as reusable libraries, re-tested Day 1 (but nothing else). here it is if you’re curious! This is written in mu, my own language I built as a self-hosted minimal compiler/vm with very few types and builtins.

https://git.mills.io/prologic/aoc2025

I finished all 12 days of Advent of Code 2025! #AdventOfCode https://adventofcode.com — did it in my own language, mu (Go/Python-ish, dynamic, int/bool/string, no floats/bitwise). Found a VM bug, fixed it, and the self-hosted mu compiler/VM (written in mu, host in Go) carried me through. 🥳

@movq@www.uninformativ.de I shrank Day 9 Part 2 from “cover the whole map” to “only track the interesting lines.” By compressing coordinates to just the unique x/y breakpoints, the grid got tiny. I still flood-fill and do the corner-pair checks, but now on that compact grid with weighted prefix sums for instant rectangle checks. Result: far less RAM, way less CPU, same correct answer.

@prologic@twtxt.net How did you optimize that? 🤔

Day 9 also required some optimizations, if you aren’t careful, you end up with really inefficient algorithms with time/memory complexity beyond what a typical machine has 🤣

Ooops, I’ve run into a bug or limitation with mu for Day 9 🤔

Day 7 was pretty tough, I initially ended up implementing an exponential in both time and memory solution that I killed because it was eating all the resources on my Mac Studio, and this poor little machine only has 32GB of memory (I stopped it at 118GB of memory, swapping badly!), This is what I ended up doing before/after:

• Before: Time O(2^k · L), memory O(2^k), where k is the number of splitters along a reachable path and L is path length. Exponential in k.
  
• After: Time O(R·C) (or O(R·C + s) with s split events), memory O©, where R = rows, C = columns. Polynomial/linear in grid size.

@shinyoukai@neko.laidback.moe Good 😊

I just completed “Printing Department” - Day 4 - Advent of Code 2025 #AdventOfCode https://adventofcode.com/2025/day/4 – Again, I’m doing this in mu, a Go(ish) / Python(ish) dynamic langugage that I had to design and build first which has very few builtins and only a handful of types (ints, no flots). 🤣

I just completed “Lobby” - Day 3 - Advent of Code 2025 #AdventOfCode https://adventofcode.com/2025/day/3 – Again, I’m doing this in mu, a Go(ish) / Python(ish) dynamic langugage that I had to design and build first which has very few builtins and only a handful of types (ints, no flots). 🤣

@shinyoukai@neko.laidback.moe Funny you should say that, I designed a new Prolog(ish) Symbolic Reasoning Engine and DSl over the holidays 🤣

Porreiro do Taço

That’s some cool science in @xuu@txt.sour.is’s backyard: https://youtu.be/bzBcs0jv9G4

H… Ho… How have I not heard about vim-tagbar before? 😳

https://github.com/preservim/tagbar

Let’s see 😂

Bought more cheap slot plates (with bad reviews and people complaining about the pin order, because I could’nt find a product without such reviews), but those are simply correct now and just work. 🤪

(Well, one part late in the calendar might need floats, depending on how you solve it …)

@prologic@twtxt.net You won’t need floats, but 64 bit integers are mandatory. 😅

Did I mention mu only supports ints? 🤔 I’m not sure if I’ll need flots for this year’s AoC? 🤔

I’m having to write my own functions like this in mu just to solve AoC puzzles :D

fn pow10(k) {
    p := 1
    i := 0
    while i < k {
        p = p * 10
        i = i + 1
    }
    return p
}

I just completed “Gift Shop” - Day 2 - Advent of Code 2025 #AdventOfCode https://adventofcode.com/2025/day/2 – But again, I’m solving this in my own language mu that I had to build first 🤣

@prologic@twtxt.net Whoop, whoop! Nice! And welcome back. 😅

I’m seeing crashes in the 3D subsystem. (Gallium? Glamor? Whatever other Mesa thing they have? No idea.) In the logs I find this:

malloc(): unaligned tcache chunk detected

And that’s why I still care about Rust and want to learn more about it, even though it’s giving me so much headache and I’ve given up so many times. Because Rust currently seems to be the only popular systems programming language that tries to eliminate these error classes.

And of course “the Rust experiment” in the Linux kernel has recently been concluded as “successful”, so that alone is reason enough for me:

https://lwn.net/Articles/1049831/

I just completed “Secret Entrance” - Day 1 - Advent of Code 2025 #AdventOfCode https://adventofcode.com/2025/day/1 — However I did it in my own toy programming language called mu, which I had to build first 🤣

That’s the right answer! You are one gold star closer to decorating the North Pole. [Continue to Part Two]

Whoo! Making progress! With AoC 2025 solutions implemented in my own toy language 🤣

Ahh that’s because I forgot to call main() at the end of the source file. mu is a bit of a dynamic programming language, mix of Go(ish) and Python(ish).

$ ./bin/mu examples/aoc2025/day1.mu 
Execution failed: undefined variable readline

Come back from my trip, run my AoC 2025 Day 1 solution in my own language (mu) and find it didn’t run correctly 🤣 Ooops!

$ ./bin/mu examples/aoc2025/day1.mu
closure[0x140001544e0]

And I’m back from my holidays! 🥳 Back to work boo 😒

Using #Python’s #pathlib to compare two repos and get back some missing files from a “recovered” version of a repo (mostly stuff in .gitignore that is handy not to discard right now).

from pathlib import Path

a = Path('sketch-a-day')
b = Path('sketch-a-day_broken')

files_a =  {p.relative_to(a) for p in a.rglob('*')
    if '.git' not in str(p)
    if 'cache' not in str(p)
    if 'checkpoint' not in str(p)
}
files_b =  {p.relative_to(b) for p in b.rglob('*')
    if '.git' not in str(p)
    if 'cache' not in str(p)
    if 'checkpoint' not in str(p)
}
missing = files_b - files_a

for p in missing:
    (b / p).rename((a / p))

Alright, Advent of Code is over:

It’s been quite the time sink, especially with the DOS games on top, but it was fun. 🥳

In case you’re wondering: All puzzles (except for part 2 of day 10) were doable in Python 1 on SuSE Linux 6.4 and ran in a finite time on the Pentium 133. Puzzle 10/2 might have been doable as well if I had better education. 🤣

@bender@twtxt.net agreed

@aelaraji@aelaraji.com probably a bug on my end with the bridge. I’ll figure it out with your help when I get home from my holidays.

@shinyoukai@neko.laidback.moe it was a mess, we are better without it. Until a new mobile client comes (not holding my breath), Yarn is very usable on the mobile, just using the browser.

@bender@twtxt.net that’s kind of what I was getting it initially yeah

@movq@www.uninformativ.de this is brilliant!

Webp, though it has been around for a long while, wasn’t fully supported on all browsers until recently. The other formats have been in use for such a long time, proving to work just fine, that the advantages Webp provides haven’t been seemingly enough to merit a switch.

Google is also the one behind Webp, and, well, people don’t trust, nor like, them much.

@zvava@twtxt.net looking sweet!

@movq@www.uninformativ.de @zvava@twtxt.net I think people get sick of everything changing all the time and so don’t bother adopting things to change when things are already good enough 🤷

@prologic@twtxt.net Yeah, but isn’t it from 2010? No widespread adoption after 15 years? Is there that much inertia? 🤔 On my box, everything just works – browser, GIMP, ImageMagick, imlib2, … 🤔

Ba Na Hills and it’s basically clouds at this point 🤣

@movq@www.uninformativ.de I think WebP being new just hasn’t seen widespread adoption everywhere (yet) 🧐

i’m always open to suggestions: PRs also welxome 🤣

@zvava@twtxt.net come on, bbycll, come! :-P

Searching the web a bit brings up lots of threads where people hate WebP. The problem being that browsers support WebP but other programs tend to be problematic … ? 🤔

@lyse@lyse.isobeef.org Yeah, no idea why that is. 🤔

@lyse@lyse.isobeef.org Nice! 🌇
